4.2 Generalized Variables

A generalized variable or place form is one of the many
places in Lisp memory where values can be stored. The simplest place
form is a regular Lisp variable. But the CARs and CDRs of lists,
elements of arrays, properties of symbols, and many other locations
are also places where Lisp values are stored. For basic information,
see Generalized Variables in GNU Emacs Lisp Reference Manual.
This package provides several additional features related to
generalized variables.
